Abstract

In this paper, we have analyzed TCP packet transmission time of IEEE 802.11 MAC DCF protocol for wireless LANs a proposed enhanced backoff algorithm. It is considered the transmission time of TCP packet on the orthogonal frequency division multiplexing (OFDM) in AWGN channel. Also, to simulate wireless LANs system, we have assumed that three stations are operated, respectively. From the results, a proposed enhanced backoff algorithm produces a better performance than an original backoff in wireless LAN environment. Also, in OFDM/QPSK (12 Mbps and 18 Mbps) channel, we can achieve that the transmission time in wireless channel decreases as the TCP packet size increases and we can infer the correlation between packet size and the transmission time, allowing for an inference of the optimal packet size in the TCP layer
